THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 IR Receiver Modules for Remote Control Systems FEATURES • Height of 0.8 mm • ± 75° half angle sensitivity • Low supply current • Photo detectors and preamplifier in one package • Internal filter for PCM frequency • Supply voltage: 2.5 V to 5.5 V, typically even 2.0 V to 5.5 V is possible • Improved immunity against ambient light • Insensitive to supply voltage ripple and noise • Material categorization: For definitions of compliance please see www.vishay.com/doc?99912 DESCRIPTION The TSOP572.., TSOP574.. series are miniaturized receiver modules for infrared remote control systems. A PIN diode and a preamplifier are assembled on a lead frame, the epoxy lens cap is designed as an IR filter. The demodulated output signal can be directly decoded by a microprocessor. The TSOP572.. is compatible with all common IR remote control data formats. The TSOP574.. is optimized to suppress almost all spurious pulses from energy saving fluorescent lamps but will also suppress some data signals. This component has not been qualified according to automotive specifications.
